Shouldnt it be PCI-E 3.0? Im on the Asus P8Z68V/GEN3 which has proper PCI-E 3.0 support and the card itself supports it too. Is GPU-Z displaying it wrongly or is it an issue with my mobo? Should I try updating my mobo BIOS?

It's because the driver is not validated yet for your platform. Same story as with X79 (maybe that's changed by now).

Does that mean the advantages of PCI-E 3.0 are not being taken advantage of right now? Although I doubt it'll really make THAT much of a difference in performance gain.

Thanks! Will check it out. Then again maybe i'll just leave it alone in the end.

Assuming your sig is correct and you have a sandybridge processor you will not be able to get PCI-e 3.0 BW as the pci-e 3.0 lanes originate from the CPU . if you dont have an IB CPU you really do not have PCI-e 3.0 lanes, even if your board is gen 3 certified. You would need to pair it to a IB processor to get PCI-e 3.0 bandwidth
